Special Issue Information

Dear Colleagues,

The diversity of new intensive and super-intensive systems in aquaculture production has imposed higher stocking densities, leading to stress induction and outbreaks of various infectious diseases. Many fish/shellfish farmers are routinely using chemotherapeutic agents, including antibiotics, to reduce the impact of infectious diseases, but application of chemical substances can give rise to numerous problems including bacterial resistance, environmental pollution, and chemical residues in the carcasses. Nowadays, the  demand, globally, is to consume chemical-free aquaculture productions and, thus, use of dietary supplements or additives capable of improving fish health condition is a vital demand. Recent research works clearly show that application of medicinal herbs/plants has great potential and they can be considered as an alternative to the use of chemotherapeutic drugs in aquaculture due to their various benefits, including growth promotion, antioxidant activity, antimicrobial- and immune effects, and disease resistance. For this Special Issue, “Phytotherapy of Infectious Diseases in Aquaculture”, we will collect scientific works from a broad range of research fields to better understand the current challenges, opportunities, and successes in this research field.

Suitable topics for contributions to the Special Issue include:

  • Phytotherapy of Gram-negative bacterial diseases in aquaculture
  • Phytotherapy of Gram-positive bacterial diseases in aquaculture
  • Phytotherapy of viral diseases in aquaculture
  • Phytotherapy of protozoan diseases in aquaculture
  • Phytotherapy of metazoan parasitic diseases in aquaculture
  • Efficacy of medicinal herbs on the immune status of fish
  • Efficacy of medicinal herbs on the immune status of shellfish

Lactococcosis, particularly that caused by Lactococcus garvieae, is a major re-emerging bacterial disease seriously affecting the sustainability of aquaculture industry. Medicinal herbs and plants do not have very much in vitro antagonism and in vivo disease resistance towards lactococcosis agents in aquaculture. Most in vitro studies with herbal extractives were performed against L. garvieae with no strong antibacterial activity, but essential oils, especially those that contain thymol or carvacrol, are more effective. The differences exhibited by the bacteriostatic and bactericidal functions for a specific extractive in different studies could be due to different bacterial strains or parts of chemotypes of the same plant. Despite essential oils being shown to have the best anti-L. garvieae activity in in vitro assays, the in vivo bioassays required further study. The extracts tested under in vivo conditions presented moderate efficacy, causing a decrease in mortality in infected animals, probably because they improved immune parameters before challenging tests. This review addressed the efficacy of medicinal herbs to lactococcosis and discussed the presented gaps. Full article
